To the pinion E is attached-the connectinglrd F, whichA gives motion to the double bell-crank Gr, the outer erinv 2 of which gives 'e latera-Lvibratory motionto the upper screen-case A,`bymea.ns of o. proper link or rod, H, while its inner e.r1n,`3, cuses the lower or cocklefscreen I to"rock,v with an oscillating and sliding motion on the rocker-blocked, which motion is obtained from the inner arm' 3, by the connecting-rod V K en a in with the rear end of the screen. The u er screens, L, instead of beine secured to certain osig g g PP e P tions, by sliding in fixed groo'vestherein, are provided withthe jaws M, upon their upper inner corners, which engage with the shoe B, while the outer ends may be inclined' to any necessary slope, and there held, by'tightf enin'g the sides of the screen-case A-against them, by means of the bolt C and nut D.
